WebSafety Instrumented Functions are alternatively referred to as Instrument Protective Functions, or IPF s. A Safety Instrumented System, or SIS, is a collection of SIFs designed to bring an industrial process to a safe condition … WebA higher SIL Level means a greater process hazard and a higher level of protection required from the SIS. To generalize how SIL Level is determined, see Figure 1. SIL Level is a function of hazard frequency and hazard severity. Hazards that can occur more frequently or that have more severe consequences will have higher SIL Levels.
